Abstract

The present study aims at assessing the correlation between the regional cerebral blood flow and the functional state of the afferent and efferent conductive systems in 12 patients with hemispheric cerebral infarctions. All patients underwent a battery of tests: Tc-99m-HMPAO SPECT, somatosensory evoked potentials (SSEP), motor evoked potentials (МЕР), and sympathetic skin responses (SSR). The above mentioned investigations were performed twice: 48 hours and two weeks after the cerebral infarction onset. The positive correlation between the regional cerebral blood flow (rCBF) and the electrophysiologic parameters reflected the presence of a moderate dependence between the cerebral perfusion changes and neural conductivity.
